Abstract ：
针对室内低浓度甲醛（～0.2 mg/m~3）的净化处理，选择两种不同孔径分布的活性炭，通过红外光谱（FT-IR）、比表面积及孔径（BET）测试和扫描电镜（SEM）分析，两种活性炭为同材质炭，孔容占比分别为：中孔炭（A）的微孔容积占比为9%(V_(Micro)/V_(Total)），中孔容积占比为91%(V_(Medium)/V_(Total)）；中微孔炭（B）的微孔容积占比为72%(V_(Micro)/V_(Total)），中孔容积占比为28%(V_(Medium)/V_(Total)）。利用静态法评价装置对活性炭样品吸附低浓度甲醛性能进行测试。结果表明，湿度变化对活性炭吸附低浓度甲醛基本没有影响；小范围的温度变化对不同孔径活性炭的吸附速率有较大影响；多次注入低浓度甲醛的测试表明，中微孔炭的吸附容量要显著高于中孔炭；甲醛脱附测试表明，中微孔炭的脱附量远小于中孔炭，对比两种活性炭的孔容，可以认为，微孔孔容有助于低浓度甲醛的吸附和锁定。

Abstract ：
Pyrochlore W2O6 center dot H2O were successfully prepared via a facile and rapid hydrothermal process in the presence of fluorinion. It is worth noting that our developed method can efficiently overcome the tedious process in the preparation of nanostructured tungstic oxide in the previous reports. The as-prepared samples have been characterized by XRD, SEM and TEM. Results showed the morphologies of the samples were nanoplate and the thickness of the plate was estimated at about several nanometers. TEM image further revealed that the plates were trigonal-like with equal lengths of about 300 nm. Furthermore the selected area electron diffraction ( SAED) pattern taken from a single nanoplate indicated that the nanoplates were the single crystals with a preferential growth direction along the [011] direction. The effect of the additive ions on the formation has also been discussed. It was found that the fluorinion played a key role in the formation of W2O6 center dot H2O nanoplates. It is hoped that our work could provide a new insight into the facile and rapid preparation of metal oxide nanomaterials.

Abstract ：
Nanocrystalline SrSiO3 with different morphologies was first selectively prepared by a facile template-free solvothermal method at different water/ethanol volume ratios. The as-prepared samples were characterized by X-ray diffraction, N-2-sorption, field emission scanning electron microscopy. The results showed that the as-prepared samples SrSiO3 displayed nanoflakes in pure water while obtained nanofibres in mixed solvent of water and ethanol (the volume ratio of water to ethanol is 1:1.). The BET specific surface area of SrSiO3 nanofibre is 161.7 m(2) g(-1), which is much higher than that of nanoflake one. The mechanisms about the formations of shape-controlled SrSiO3 are proposed and discussed based on a reaction-crystallization process. As a novel photocatalyst, the photocatalytic activity of as-prepared samples SrSiO3 were evaluated by the photocatalytic degradation of orange II (20 mg L-1) and the total organic carbon (TOC) value indicated that orange II solution can be mineralized in 120 min.

Abstract ：
A visible light (490-780 nm) was introduced into the process of oxidizing CO over a TiO2 supported Au nanoparticle catalyst (Au/TiO2). It is found that the visible-light irradiation can promote the oxidation of CO over Au/TiO2. Based on the results of both the optical absorption of Au/TiO2 and the adsorption of CO over Au/TiO2, it is proposed that the localized surface plasmon resonance (LSPR) of Au nanoparticles induced by the visible-light would promote the adsorption of CO and its activation at the surface of Au species, resulting in the promoted oxidation of CO over Au/TiO2.

Abstract ：
Polyaniline/Bi3NbO7 nanocomposites were successfully prepared by a simple chemisorption approach. Their particle sizes ranged from 25 to 50 nm. The photocatalytic activities of the as-prepared samples for the rhodamine B degradation were evaluated under visible light (420 nm <= lambda <= 760 nm). The results indicated that the samples exhibited excellent photocatalytic activities and high activity stabilities for the degradation of rhodamine B. When the loading amount of polyaniline was 4 wt%, the obtained sample showed the highest photocatalytic activity. Its photocatalytic activity was also much higher than that of the reference sample (TiO2-xNx powders). On the basis of the experimental results, photo-generated holes were detected as the main oxidation species responsible for the decomposition of rhodamine B over polyaniline/Bi3NbO7. Furthermore, the enhanced photocatalytic activity was mainly ascribed to the synergetic effect between polyaniline and Bi3NbO7. (C) 2012 Elsevier B.V. All rights reserved.

Abstract ：
Novel visible-light-driven Al/BiVO4 photocatalysts were synthesized via a facile hydrothermal method for the first time. The samples were characterized by X-ray diffraction, N-2-sorption, UV-vis diffuse reflectance spectra, scanning electron microscopy, high-resolution transmission electron microscopy, Fourier transformed infrared spectra and X-ray photoelectron spectroscopy. The photocatalytic activity of the samples was evaluated by the decomposition of methylene blue under visible light irradiation (400 nm < lambda <580 nm) and was compared with that of single-phase BiVO4. The results revealed that the introduction of Al can improve photocatalytic performance greatly and different concentration of Al resulted in different photocatalytic activity. The highest activity is obtained by the sample with a doping concentration of 12 at%. The reason for the enhanced photocatalytic activities of Al/BiVO4 samples was also discussed in this paper.

Abstract ：
High efficient photocatalytic reduction of 4-nitroaniline to p-phenylenediamine over microcrystalline SrBi2Nb2O9 was observed upon purging with N-2 under UV-light irradiation. Its photocatalytic activity was higher than that of sample P25 (commercial TiO2, Degussa Co.). The analysis results of X-ray diffraction and X-ray photoelectron spectroscopy revealed that microcrystalline SrBi2Nb2O9 had high stability for the photocatalytic reduction of 4-nitroaniline. Further experiments indicated that ammonium oxalate was indispensable for the photocatalytic reduction of 4-nitroaniline. Moreover, the high efficient photocatalytic reduction of 4-nitroaniline over microcrystalline SrBi2Nb2O9 might be ascribed to its relatively high conduction band. (C) 2011 Elsevier B.V.
